TJA1050: There is a current limiting circuit to protect the output stage of the transmitter, so that the short circuit caused by the positive or negative power supply voltage accidentally will not damage the TJA1050 (at this time, the power consumption increases). TJA1050 also has a temperature protection circuit. When the temperature of the connection point with the transmitter exceeds about 165 ?, the connection with the transmitter will be disconnected. Because the transmitter consumes most of the power, the power consumption and temperature of this integrated circuit will be lower. However, other functions of the IC still work. When the pin TXD becomes high (level), the transmitter resets from the off state. This temperature protection circuit is especially needed when the bus is short circuited. SJA1000?
